Yes the epoxy sticks really well to PLA. I use wax which makes the epoxy release from most materials, but it doesn't work with PLA, you will need a proper release agent. If you are using a good CAD package, you can design the part, then the moulds for both sides. Matched die moulding is a super way to make high quality carbon parts.

This was in the trending tab for me.

why is this 3 year old video trending, and why am I watching it?

I used PLA, so these parts are limited by the weak material under the carbon. I hoped I could get it out using boiling water, it goes soft but very rubbery and hard to remove. I will try soluble PVA one day to make pure carbon parts.

gr8 work, thanks for the sharing, bravo

great video. Have you tried reinforcing the 3d printed plastic itself without carbon fabric? I wonder if making it porous and putting some sort of resin will make pla or abs moderately strong yet keeping the looks.

A really great idea! Now I have to think how I'll use it! LOL

so the epoxy glues to the PLA quite well it seems. I was thinking about creating inverse shapes, and coat the molds with laminate. It probably will only work if one uses a seperation agent..

nice! are you using PLA or ABS?

How were those angles determined? How did you determine how far apart they needed to be?

very....very nice.....congratulations....... São Paulo - Capital - Brasil

hi can u tel me what is the thickness of the inner wall of that pipe thats bent and also what material is it made of thanks.

thats some heavy breathing, you okay man?

graphene

Useless in my mind, in a few short years that plastic will just crumble away.

You mean carbon fiber..
